Applications of Heat Exchanger

Heat exchanger are found in most chemical, electrical or mechanical systems. They serve as the system's means of gaining or rejecting heat. Some of the more common applications are found in heating, electronic equipment, ventilation and air conditioning (HVAC) systems, radiators on internal combustion engines, boiler, condenser, and as pre heaters or coolers in fluid systems. The associated web pages will review some specific heat exchanger applications. The intent is to provide several specific examples of how each heat exchanger functions in a system, not to cover every possible application
